Double Coated Window Butyl Tape
1. Window Seal Brief
Solvent-free butyl sealing material for window and building-panel interfaces.
2. JIS Data Record
| Window roll geometry | One-millimetre gauge; 10 to 1000 mm width; 15 m length |
|---|---|
| Gauge used in the recorded test | Half a millimetre |
| Stainless peel result | Fifty newtons across 25 mm at 180 degrees, based on JIS 0237:2000 |
| Lateral adhesion result | Forty-three newtons per square centimetre |
| Vertical retention setup | 110 minutes using 200 g on a 10 by 20 mm bond |
| Recorded extension | Nine percent under the cited JIS basis |
| Substrate comparison climate | 23 degrees Celsius with a two-degree tolerance |
3. Frame Substrate Map
Reported adhesion values are 48 N/25 mm on stainless steel, 36 on veneer, 35 on nonflammable board, 33 on calcium silicate board, 48/54 on the face/back of PVC-coated steel and 54/57 on colour-coated steel.
4. Double-Coating Control
Butyl mixing, double-face coating and width conversion determine equal adhesion on both sides for the cited No.9805 construction. Liner and winding control protect wide-format rolls.
5. Thickness Reconciliation
Reconcile the 1 mm standard format with the 0.5 mm test-table entry before approval. Repeat peel on the actual window frame and check water entry after movement.
6. Window Order Inputs
Specify gauge, width, 15 m roll confirmation, frame substrates, liner and OEM artwork. Request the exact grade report rather than combining data from different thicknesses.
7. Specification Questions
Do both faces have the same adhesion?
The source says both sides of No.9805 have the same adhesion.
Why must thickness be clarified?
The format table lists 1 mm while the performance table records 0.5 mm.
8. Face-Test Outlook
Window-system procurement is placing more emphasis on face-by-face substrate data and test thickness, preventing headline peel values from being applied to every construction.
